Abstract

Se refiere a un método para adaptar el protocolo de comunicaciones a las condiciones actuales del canal de comunicaciones en una disposición digital decomunicaciones. Un formato digital de comunicaciones se adapta óptimamente a una condiciónactual del canal de comunicaciones. Una velocidad efectiva debits de de mensaje sustantivo transmitidos por unidad de tiempo varía para agregar o quitar bits de protección de mensaje según cambia la condiciónactual del canal. Sin embargo, elnúm ero total de bits de mensaje y bits de protección de mensaje transmitidos por unidad de tiempo no cambia. Sedetermina una calidad actual del canal de comunicaciones entre dos dispositivos de comunicaciones. Se varía una relaciónde b its de mensajesustantivo y bits de protección de mensaje para adaptarse a esa calidad actual determinada del canal. La relación es mayor para canales de comunicaciones demayor calidad que para canales de comunicaciones de menor calidad.También se refiere a una disposición para llevar a la práctica dicho método.Refers to a method of adapting the communications protocol to the current conditions of the communications channel in a digital communications arrangement. A digital communication format is optimally adapted to a current communication channel condition. An effective rate of substantive message debits transmitted per unit of time varies to add or remove message protection bits as the current condition of the channel changes. However, the total number of message bits and message protection bits transmitted per unit of time does not change. A current quality of the communication channel between two communication devices is determined. A ratio of substantive message bits and message protection bits is varied to accommodate that particular current channel quality. The ratio is higher for higher quality communication channels than for lower quality communication channels. It also refers to a provision to implement such a method.
